The ACLU lawsuit filed Monday says Mississippi's Religious Liberty Accommodations Act discriminates against LGBT people by allowing businesses to deny services or employment based on sexual orientation. The ACLU says HB 1523 even sanctions discrimination against straight people who have sex outside marriage, but that part of the law isn't targeted in this new lawsuit.

Others say it protects people from being forced to go against their religious beliefs.

"The bill simply says the government of the state of Mississippi and its political subdivisions cannot discriminate against people of faith who hold deeply held religious beliefs," the governor of Mississippi told The Daily Signal.

"Also, being black and gay, we always learned, growing up, about the civil rights movement. ... We thought this movement was over. We thought that we would be fine," Nykolas Alford told The Clarion-Ledger.
